How to use DUSH MASTICS.
Follow these steps for best results.
Remove dust, loose material and any contamination from the crack or joint using a dry brush or compressed air.
Combine DUSH MASTICS base with the hardener at the correct ratio. Work quickly — pot life is 3–5 minutes.
Apply into the crack or joint, overfill slightly, allow to cure hard (3–5 min), then grind and sand flush to the surface.
Pro tips & common mistakes.
Do This
- Mix both components in the exact ratio stated on the label
- Work in small batches to stay within the product's pot life
- Apply slightly proud of the surface and grind flush after full cure
- Clean tile faces immediately — before epoxy begins to harden
- Keep marble dust and contamination out of the joint before filling
Avoid This
- Try to extend pot life by refrigerating mixed epoxy — it doesn't work
- Apply polyester adhesive over damp or oily surfaces
- Skip the patch test when colour-matching a new marble shade
- Use standard cement grout where epoxy grout is specified
- Grind filled joints before the product has reached full cure strength
